Answer:
Explanation:
fluorine have gained one electron that is why the sign is -1. they both have different number of protons. They have different neutron numbers. F have 10 and O have 8.

Answer:
Sunlight, Soil, Rocks, Temperature and dead deer
Explanation:
You could say the dead tree is now an abiotic factor because biotic factors refer to living things
Answer:
Answers are given below.
Explanation:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1) 0.680 moles of H₂S
0.680 mol × 6.022 × 10²³ molecules / 1mol
4.09× 10²³ molecules
2) 8.96 moles of KI
8.96 mol × 6.022 × 10²³ molecules / 1mol
53.96 × 10²³ molecules
3) 6.500 moles of KClO
6.500 mol × 6.022 × 10²³ molecules / 1mol
39.143 × 10²³ molecules
4) 0.950 moles of NaOH
0.950 mol × 6.022 × 10²³ molecules / 1mol
5.721 × 10²³ molecules
5) 4.73 moles of Na₂CO₃
4.73 mol × 6.022 × 10²³ molecules / 1mol
28.48 × 10²³ molecules
